Right, there is indeed only a summary of the cached entries, and the 
whole content is not dumped. I'm afraid there is currently no way to 
retrieve the content. It might be a bit tricky to dump it to a file 
since DNS messages contain binary content, what are you looking for 
exactly? I guess we would need some kind of framing (protocol buffer, 
perhaps? That would be consistent with DNSTAP and our own remote logging 
format). Please feel free to open a feature request on our GitHub [1], 
and even a pull request if you are willing to write a bit of C++ :)
